JAR AND CLO-SRE THEREFOR.

' vented new and useful Improvements in Jars and Closures Therefor, of which the following is a specification. y y

The invention relates to a receptacle, and more particularly 4to the class of bottle or jars and closures'therefor.

. l The primary object of the invention isthe provision of a closure for bottles or Jars 1n which the mouth of the latter may be hermetrically sealed so as to provide HuidW tight juncture between the closure and the body of thebottle or jar, thus obviating any .pos-

' sibilit-y of'the admission of air, dampness or liquid within such body, thereby preserving the contents therein.

Another obj ect of the invention is the l'pro-4 4 vision of a j ar and closure of the characterV described, in which rubber washers or gaskets ofthe ordinary resilient type may be employed, whereby on the application of the cap or closure to the body of the jar the said washer orgasket will be compressed between the sa1ne,thus effecting a fluidy tightclosure at the mouth of the jar so as to prevent egress of the contents .thereof or ingress of foreign matters therein. A

AA further object of t-he invention is the provision of a jar and closure therefor in which the latter will be held against any possible lateral displacement whenapplied to lthe mouth of the jar and also that will enable the sealing of such a jar for the preserving of the food orother substances contained therein. .l

A still further object of the invention is the provision of a jar and closure therefor in which access may be easily had tQ the interior of the jar forthe cleaning thereof to render the same sanitary, the closure being readily applied and removed from the jar at will `and when applied is designed/to seal theysaid jar so asto make the same fluid tight. 1

In the drawings accompanying and .forminga part of this specification is illustrated the preferred forms of embodiment of the invention, which to enable those skilled. in

the art to carry the invention into practice.

will be set forth at length inthe following I Specication of Letters Patent.' Patented Feb, 21, 1911, ,Application filed August 19, 191.0. Serial No. 577,99lll.`

de-tail description, while the novelty of the invention will be 'pointed out in the claims succeeding the description.. It is, of course v tor be understood that changes, variations and modification may be resorted to, such as come within the scope vof the .appended claims without departing from the spirit of the invention or sacrificing any of its `advantages. l

In the accompanying drawings Figure l is a vertical longitudinal sectional view through the jar and closure constructed in accordance with the invention. Fig. '2 is a side elevation ofthe closure or stopper re. moved from the jar and the rubber gasket or washer detached therefrom. Fig. 3 is a perspective view of the. riibber gasket or washer. Fig. Lfis avview similar to 2 the washer or gasket being mounted thereon .prior to its insertion in the jar. FigJ- is a fragmentary side elevation of a jar and closure therefor showinga slight-'modification of the invention, the jar and closure being partly broken away.

Similar reference characters indicate corresponding parts throughout the several, 'views of .the drawings.

Referring to the drawings by numerals, 5

Vdesignates the body of a jar or the like,

preferably constructed from glass, although the same may be made from any other suitable material, the cylindrical vertical wall of the jar being of Iuniformdiameter throughout the length of the latter so that the said jar may be readily cleaned for sanitary purposes. The jar at its mout-h is provided with a rounded edge 6, the purpose of which-will hereinafter more fully be described. f

Detachably fitted in the mouth of the body 5 is a closure comprising 4a. stopper body 7 which is constructed from any suitable material, although preferably made from glass, the body 7 beingy reduced for substantially one-"half of its depth to forma contracted cylindrical portion 8 with respect to its remaining portion and also to provide a bearing shoulder 9, the latter being adaptedl to contactwith the upper roundedl edge 6 of the body of the'jar when the cap or closure is inserted therein, thus limiting the insertion of the contracted portion 8 lwithin the said body 5 of the jar.`

respectively, spaced from each in the latter. face or rib 13 said closure The peripheral edge ofthe rim .portion of the closure or stopper 7 is provided with a knurled or roughened surface 10, whereby Vthe said closure or stopper'may be gripped and the latter turned when inserting the same in the body of a jar or removing it therefrom. The closure or stopper 7 in the periphery of its contracted portion S is provided with spaced annular channels or grooves 11l and 12, respectively, providing annular bearing ribs or surfaces 13 and 14, other, the bearingrib or surface 111' being of less ldiameter.. than the rib or bearing surface 13 so that when the closureV onstopper 7 is -inserted within the mouth of the body 5 of the jar, the said bearing rib 13 will frictionally contact with the interior surface or wall of thex said body so that there will not be a'ny possibility of lateral displacement ofthe said closure or stopper when engaged Also this'annular bearing sur- When contacting with the inner surface of the body of the jar will prevent the contents of the latter from leaking'into the channels or grooves 1l and 12 formed in the or stopper. Within the channelor groove 11 is seated the inner peripheral 4 edge 15 of a resilient-washer or gasket 16 so than on introducin the closure or stopper 7 within the meuh of the jar, the said washer orgasket, 16 will be compressed between the annular bearing surface 14 and the body 5 ofthe jar, thus serving as a sealing medium between the closure and the jar. Should this gasket or washer 16 be coinpressed to an excessive degree upon insert- I ing the closure-or stopper in the jaw its outer` peripheral edge 17 will be squeezed into the channel or groove'12 which latter is provided to accommodate the same. o

The stopper'or closure 7 'in the inner face of the -contracted portion is provided with a centrally located concaved recess 18 which is provided to give space for air that may exist within thebody 5'of the jar, thus the air being displaced on the insertion of the closure O15-stopper withinihennouth ofthe l Ajar. However, this, recess 18 may be dis, pensed with if deemed desirable.

In Fig. 5 there is shown a slight modification of the invention wherein the neck portion 19 of the body of a -bottle or jar is formed with an annular flange 20.spaced from the mouth edge of the neck portion andin thesaid neck portion between `the flange and the mouth edge fare provided, spaced annular grooves or channels 21 and 22,.respect'ively, the channel 21 receiving the inner peripheral edge 23 of a rubber gasket or washer 24. Between the channels or grooves 21 and 22 is an annular bearing rib 25 against which is compressed the washer l the'gasket or 4becomes compressed and folded orl gasket 24.- on the mounting of the inverted cup-shaped cap'26 upon'the neck portion of the jar, the cap 26 being provided with knurled or Toughened surfaces 27 to permit the same to be `readily applied tothe jar and removed therefrom when required. This cap 26 when applied to the neck portion 19 of the has its flanged portion engaged with the surfaces of the gasket 24.1, depressing the same between the said flanged portion of the said cap and the bearing rib 25, thus sealing the jar whereby, it may be rendered fluid tight.

On moilnting the cap 26 upon the jar, washer 24 being normally llat between it and the body of the jar so that the outer peripheral edge 28 of the washer or gasket will be squeezed into the channel or groove 22 in the neck portion 19 ofthe jar for the reason that on the spreading of the gasket or Washer its outer peripheral edge 2,84 will abut against the flange 20l directing it inwardly within the channel or groove 22, as the cap is being forced onto the jar. Thus it will be seen that when the cap is forced onto the jar, thel gasket or washer 24 will serve as a sealing medium to 'render the Jjar fluidntight therebypreserving the contents 'ofthe same.

Should the closure vor stopper become 'stuck' of the jar 1t `is only neceswithin the mouth too'l between the rounded sary to insert -a edge'of the body of the/jar andthe rim portion of the closure or stopper then by depressing thejool the stopper or closure is lift'dfom the mouth of the 'j ar.

" Itristhouglitthat fro ,the .foregoing the constructionand operation of the invention will be clearly understood, and a more extended explanation of the'same has therefore -beenomitted.

Having thus described theinven'tion that I claim as new is 1. The combination witli intertitting meinbers, of a resilient gasket interposed between 'the' members, one of said members being provided VVwith spaced annular channels receivv edges of- ",-and nltturned annular flange mg the inner and outer peripheral on themember containing said channels and contiguous thelone adapted to receive the' h outer peripheral edge of the gasket for' defleeting channel.

l 2. The combination with a receiving member and a closure member therefor, of a normally contracted expansible gasket interposed between said members, one of fsaid members being provided with an annular rib rabbeted from the contiguous face of the other member; and also provided with an'- nular channels spaced apart by the-said rib, the said gasket being-held in 'one channel at its inner periphery and adapted to be distorted by the rib in the direction of the otherrchannel, and a detlecting surface on the outer edge of said gasket in its the member containing the channels to guide In testimony whereof I aix my signatre the outer edge of the gasket into its channel, ywhereby the gasket, when engaging therespective channels, will be sustained eom-l 5 pressed and limited in its expansion between Witnesses: i the members when ntertted with each FRANK C.
